RF Micro Devices Introduces Dual Band Low Noise Amplifier/Mixer With Frequency Doubler for TDMA Handsets

Source: RF Micro Devices

Las Vegas, NV. RF Micro Devices, Inc. (Nasdaq: RFMD), a leading provider of proprietary radio frequency integrated circuits (RFICs) for wireless communications applications, announced today, at CTIA Wireless 2001, the availability of the RF2475 dual band low noise amplifier/mixer with frequency doubler and transmit local oscillator (LO) outputs for TDMA handsets.

"The RF2475 was designed to meet evolving system requirements of TDMA handset manufacturers. With its dual band capability, good RF performance, full feature set and excellent noise figure, the RF2475 enables TDMA handset designers to efficiently achieve their design goals," said Brent Wilkins, marketing manager for digital cellular products at RF Micro Devices. "Additionally, the frequency doubler reduces component count and therefore cost and board area, making the RF2475 a low cost, high-performance solution for the receive function - one of the more challenging functions in the phone."

The RF2475 s frequency doubler reduces the number of voltage controlled oscillators (VCOs) required in the phone, while the LO output buffers eliminate the need for external drivers for the LO signal feeding the transmit path; minimizing board area and component count.

The RF2475 is a fully featured dual band receiver, which includes two LNAs and associated down converting mixers, a frequency doubler, and dual transmit LO output buffers. The RF2475 maintains 25 dB cascaded gain and 2.2 dB cascaded noise figure for the cellular band and 26 dB cascaded gain and 2.8 dB cascaded noise figure for the PCS band. Each LNA has a gain bypass mode, which is controlled by the gain select pin increasing the receiver s dynamic range. The two mixer outputs are tied together internally, providing interface to a single IF SAW filter minimizing board area. The cellular band LO signal feeds the cellular mixer, the frequency doubler and the cellular transmit output buffer. The integrated frequency doubler provides the LO signal to the PCS mixer and feeds the PCS transmit LO output buffer.

The RF2475 is manufactured using an advanced GaAs HBT process technology and is offered in a small industry-standard 5x5mm, 28-pin leadless plastic package. Priced at $2.20 in quantities of 100,000 units, production quantities will be ready for shipment in the second quarter of 2001. Samples and fully assembled evaluation boards are available now from RFMD.
